OPTIMIZATION OF CONDITIONS FOR DETERMINATION OF BOTTOM SEDIMENT SORPTION CHARACTERISTICS ABSTRACT An option of this study was to optimize conditions of distribution coefficients determination in the water-sediment system. The study results will be applied in the task A research on influence of Temelín Nuclear Power Plant accident on the Vltava and Labe water environment contamination to the border profile Labe - Hřensko. After finding optimal conditions for sorption experiments, these will be applied on the experiments using real sediment samples and corresponding surface water extracted from different localities of Vltava River, Labe River respectively. A goal of the whole project is to contribute to creation of a crisis scenario of potential accident of Temelin Nuclear Power Plant and its impact on Vltava and Labe water environments. Above all, the aim is to answer the question which processes would take place in dams and basins during the contamination by fission and activation products, whether and which products would be preferably adsorbed and would consequently settle down and which would supposedly be transported to the lower parts of the watershed. The practical part of the...

Roček, T. Changes in income distribution in the USA and decomposition of Gini coefficient. Diploma thesis. Brno: Mendel University, 2016. Since the 80s of the last century, the United States has seen a considerable income inequality growth. This diploma thesis analyses the influence of individual income sources on determination of inequality, esteems their significance and formulates instruments that the government can use to affect these sources. This diploma thesis contains decomposition of Gini coefficient. This decomposition revealed, that the source, which is the most important determinant of the total income ine-quality are salaries and wages. Sales of assets contributed the most to the rise of inequality in the analysed period from 2000 to 2014. This income source also has the highest potential for further growth of income inequality. Discussion part, which follows, contains the debate about the main causes of this progression and the relevance of researching the income inequality issue. Based on the approach used in this diploma thesis, it is possible to decompose the Gini coefficient in any state or region, and to explore the inequality determinants in this way. This thesis also offers a comprehensive view on the whole issue.

The aim of this diploma thesis was to evaluate the influence of long-term effects of agrotechnical measures (different intensity of soil tillage, variant crop rotations and organic amendment during long-term continuous cropping of cereals) on coefficient of structure (CS). Observations were made within two long-term stationary field experiments conducted on luvisolic Chernozem soil in a suger-beet production region. During the first experiment conducted between 1989 and 2017, the impact of two crop rotations (with 33.3% and 66.6% representation of cereals) and four variants of soil tillage to winter wheat, spring barley and sugar beet were evaluated. For winter wheat and spring barley, the following soil tillage options were included: 1 – plowing up to 0.22 m; 2 – plowing up to 0.15 m; 3 – direct sowing into uncultivated soil and 4 – shallow soil tillage up to 0.10 m. The variants for sugar beet were: 1 – plowing up to 0.28 m; 2 – plowing up to 0.22 m + hoeing up to 0.40 – 0.45 m; 3 – plowing up to 0.28 m + sowing of a intercrop; 4 – plowing up to 0.22 m + sowing of a intercrop. In the second field experiment conducted between 1977 and 2017, the influence of organic amendment on the long-term continuous cropping of cereals (rotation of winter wheat and spring barley) was evaluated. Three variants of organic amendment were included: 1 – straw harvest; 2 – straw harvest and intercrop production for green manuring and 3 – straw incorporation. Measurement of the coefficient of structure was made in 2017, in the first experiment at the last crop of crop rotations – spring barley, in the second experiment at the spring barley. The influence of the crop rotation on the structural condition of the soil was small, statistically insignificant. On average, slightly higher CS values were recorded in the crop rotation with 66.6% representation of cereals. The influence of soil tillage on CS was statistically significant. The lowest CS value was recorded in variant 1 (plowing to 0.22 m for cereals, plowing to 0.28 m for sugar beet). The highest CS was recorded in variant 3 (direct sowing in to an uncultivated soil for cereals, plowing to 0.28 m and intercrop for sugar beet). The results generally show the beneficial effect of lower soil tillage intensity and growing of frosting crops on the structural state of the soil. Organic amendment has beneficially affected the structural state (CS) only in the upper part of the soil (0 – 0.15 m). Straw incorporation and straw harvest with an intercrop for green manuring had the most favorable influence on the CS. Higher CS values were measured in the top soil layer (0 – 0.15 m) in both field experiments.

The aim of this diploma thesis is to consider the maximum use of bent parts in the design of a smooth dining chair with respect to the physical and mechanical properties of Pine wood. It also compares the strength properties of the three variants of the structural bonding of the reinforcing arc with the bearings and the smooth dining chair legs. Identify the strength properties of selected structural joints in the design of a smooth dining chair and statistically evaluate the results. The bending moment and the stiffness of the joint were determined for joints. They also describe the physical and mechanical properties of Pine Forest and the production of bent parts.

In this work we study properties of branched polymers in a good solvent. We focus on problematic related to the size exclusion chromatography and predicting elution behavior of randomly branched polymers. We developed a software for generating self-avoiding walks (SAW) of any given non-looping architecture on a cubic lattice using Monte Carlo (MC) simulation and vali- date its reliability by presenting the scaling of different architectures: linear, 3-arm star and 6-arm star and asymmetric star. We calculate distribu- tion coefficients and calibration curves for size exclusion chromatography for various architectures to validate that the hydrodynamic radius is more suitable for predicting elution volume than the radius of gyration. Then we propose a new method for, although approximate, a very fast estimation of radius of gyration and hydrodynamic radius for different architecture using a graph method. It is done by comparing MC results with results obtained from graph theory. Then we introduce a correction to graph-theory results to fit the MC. At the end we present depletion layer calculation from MC and self-consistent field (SCF) method for polymers and their comparison. We show how calculation of depletion layer using SCF can be improved to get significantly better agreement with MC results. v

The diploma thesis called Revitalization of the Landscape after Mining deals with the current topic of recultivation of the area affected by mining, namely the deep mining of black coal in the territory of Karviná. The aim of the diploma thesis is to characterize the progress of one of the largest reclamation projects in the CR, the Karviná Sea, and to evaluate its success on the basis of a comparison of the ecological stability of the area before starting the mining and after the recultivation work. In order to determine the stability of the territory, two methods of calculation were used, namely a simpler calculation of the ecological stability coefficient according to Míchal, and a more precise calculation of Miklós ecological stability coefficient, which also takes into account the ecological significance of individual landscape elements. The results show an unambiguous increase in ecological stability of the area of interest after recultivation, compared to very low ecological stability in 1950.
